Is the HVAC system sufficient to stop virus spread?
Facility heating and cooling systems (HVAC systems) serve as a complement to primary COVID transmission mitigation methods (face coverings, distancing, hand washing, etc.). Research indicates that the potential for infection transmission via building HVAC systems in non-medical facilities is low, and only systems without ventilation pose a significant risk of increased transmission. We are further reducing the potential for transmission via the HVAC systems by increasing the amount of ventilation the systems supply, continuing filter changes, disinfecting interior surfaces of accessible air handling equipment, monitoring system performance, and assessing air disinfection technologies.
